It looks like we’ll be meeting more of Jean-Ralphio’s family next season on Parks and Recreation. THR reports that living TV legend Henry Winkler will be playing the dad of actor Ben Schwartz’s popular club-hobbing douchebag character, Jean-Ralphio Saperstein. The news comes a year after Jenny Slate was cast as Jean-Ralphio’s sister, Mona-Lisa, who appeared in three episodes so far. Winkler, who recently starred in the latest seasons of Arrested Development and Childrens Hospital, has signed on to appear in the first episode of Parks and Recreation’s upcoming sixth season, an hour-long season premiere set in London that airs September 26th. He’ll potentially recur on the show after that, just like Ben Schwartz and Jenny Slate have. There’s no word at this time on whether Winkler’s character will be like his kids or totally different, or what his (probably silly) name will be.
